How do I check the forum ID to display text?

Hi.

I created the two forums.

I want to show two different words check the forum ID.

For example,

If the forum ID = 100, man.

If the forum ID = 200, women.

I want to send the word to a variable placed where I want.

And I want to implement this in function.php files of child theme.

I know this is asking for help to escape the Kleo Themes range.

This is your help for me this will be a great help.

Thank you.
